This week Brett and Alice are breaking down the timeline from August 27, 1998 through January 12, 1999.  They cite Hae's diary as a source.  They don't mention where the rest of the information is coming from, but it appears they are working off of this Reddit post for pretty much the entire episode:

Key takeaways:

Inez Butler originally told police that Hae was going to pick up her cousin, and then go to work.  Not a wrestling match.  LINK TO HER POLICE STATEMENT 

Debbie Warren saw Adnan in the Guidance Counselor's office at 2:45 and then Hae in the lobby at 3pm. 

Evidence indicates that she did have the right day.  LINK TO HER INTERVIEW
